Planning Tools for Mass DepopEvents
David Cornejo
Ph.D. Candidate in Operations Research
Problem Statement
• Engineering solutions can be tested and evaluated on a small scale
• Implementation effectiveness requires taking into account system interaction.
• Simulation can estimate the resources required to scale-up process to disaster response proportions.
2
Goals
• Strategic(Before)
• Develop basic estimates of resource requirements before disaster.
• Tactical(During)
• Assist in identifying resource savings/need during event.
•Delivery via Web application
3
System Overview
•4 Distinct Stages
• Moving pigs from house to loading chute
• Loading pigs onto available farm truck
• Preparing trucks and gasification
• Disposal of carcasses
•METRIC: Time to complete process.
4
Moving Pigs from house to truck
• Influenced by following user inputs
• Pigs: Number, Weight class
• Houses: Number, Size, Loading Slot length
• Workers: Number available
• Variables affect Travel Time of run.
• Calculated travel time parameterized travel time distribution(stochastic travel time).
5
Load Truck
• Pigs Loaded onto truck
• Capacity of trucks from pig weight class
• Details
• One or more loading chutes available
6
Class Name Space Requirement(sq. ft./pig)Nursing (<50lbs) 1.09
Weaning (50-100lbs) 2.635
Finishing (100+lbs) 3.48
Breeding Boar/Sows 5.55
Preparing Trucks for Gas
•Before each application of gas some preparation (check tarp, attach hose etc.)
•Assumed to take between 5 and 10 mins
• May physically take place at gas location.
7
Administer Gas
•Correct Flow rate(20-30% of volume of container/min) applied for minimum of 5 minutes.
•Applying gas consumes available stock.
• Process halted when no more gas
• Gas can be delivered on intervals.
• Sublimation a way to extend gas stock
8
Dispose of Carcasses
• “Dwell Time” of 10 minutes accounted for in minimum travel time to Disposal Site.
• Ability to travel immediately after gas
• Trucks take time to return to loading slot

Parameters and Control Variables
• Farm Parameters• Size of House• Size of Pin• Number/Length of Load Slots
• Truck Controls• Truck Size• Number of Trucks
• Handler Controls• Number of Handler• Handler Efficiency
• Special Process Parameters• Dry Ice recovery process option

Web App Solution
• Best resource solution form a large array of scenarios batch run in simulation model.
• Results stored in database.
• Web application exposes relevant controls to decsionmaker and calculates resource requirements based on stored simulation results.
• Web app runs fast (seconds) and requires no specialized software.
